This problem is persisting, and so am I, I guess...apologies for being 
the squeaky wheel.

Can anyone verify that the SQL MA (tested from the web interface sanity 
check) is ever able to return a successful check on the latest perfSONAR 
3.3 MDM Debian install image?

I'm not doing anything out of the norm in the installation. I'm just at 
a loss to see where, if it can be installed from the latest image, I 
might have deviated from the instructions in the Administration Guide.

My configuration is that of a combined LS, RRD MA, and SQL MA options, 
chosen from the MDM installer's options.

ADVthanks!ANCE
